I shoot a cajunized SP01 in IDPA - the rules changed so that you can shoot the full length dust cover in ESP classification and, I believe, SSP classification. When I shoot production in USPSA, it's the same gun - 75 SP01. I've also got a 75 semi-compact and a 75 compact that I'll use next season in IDPA ccp class - both have been cajunized as well.
Enjoy!
